'Mad Men''s Sally Draper is one of the greatest kids on TV -- period -- and that's thanks in large part to the talented 10-year-old who plays her, Kiernan Shipka.

Now, I get the opportunity to interview some of the biggest stars, but I was positively giddy about having Kiernan in studio for this interview. She showed up ready to answer all (OK, most) of my questions, including what we should expect from Sally and the Drapers in season 4 (premieres Sun., July 25, 10PM ET on AMC) and who's the biggest goofball on the swanky 'Mad Men' set.

Kiernan also dished about which 'Mad Men' lady she'd like to have more scenes with. And just as I was listening to her sharp, intelligent answers, forgetting how young she actually is, she admitted that she doesn't exactly get to watch the whole show when it airs -- her mom, Erin, gives it a first pass to make sure it's age-appropriate.
